Eigen FAQ

How does Eigen turn my uploaded course material into a lesson?

Eigen builds a lesson around your uploaded course material by drawing diagrams, writing out equations, and working through examples step by step on an interactive whiteboard while explaining out loud. It checks your understanding before moving on and re-explains when interrupted by voice or text. This works with lecture slides, textbook chapters, practice exams, and homework problems.

Which teams or students benefit most from using Eigen?

Eigen fits best for individual students studying STEM, economics, law, languages, or preparing for MCAT, NCLEX, or LSAT exams. It is especially useful for learners who want a step-by-step, interactive explanation of complex topics and need to upload their own course materials. Teams looking for a general-purpose chatbot, coding assistant, or content generator would not find it suitable.

How does Eigen compare to Khanmigo for exam prep?

Unlike Khanmigo, which is a general tutoring assistant, Eigen specializes in building interactive whiteboard lessons from your own uploaded materials, including practice exams and homework problems. Eigen covers a broader range of subjects, including law and languages, and is designed for MCAT, NCLEX, and LSAT prep. Khanmigo may offer more classroom integration, but Eigen focuses on step-by-step visual and verbal explanations.

Can Eigen re-explain a concept if I interrupt with a question?

Yes, Eigen re-explains concepts when interrupted by voice or text. It checks your understanding before moving on, so if you ask a question mid-lesson, it will pause and address your confusion. This interactive loop ensures you grasp each step before proceeding.

What are the main limitations of using Eigen for education?

Eigen is not designed for general-purpose tasks like coding assistance or content generation, so it won't replace a versatile AI assistant. It also lacks LMS integration and classroom management features, making it less suitable for educators who need to track student progress within a school system. Its focus is strictly on one-on-one tutoring and exam prep.

How is Eigen priced for students?

Eigen is available on a free tier, with paid plans that provide more usage and features. The free tier lets you start using the core tutoring functionality, while paid plans are designed for heavier use and access to additional capabilities. Specific pricing details are not provided here, but the model is freemium.

Does Eigen support voice interaction for asking questions?

Yes, Eigen supports both voice and text interaction. You can interrupt the lesson by voice or text, and Eigen will re-explain the current step. This makes it easy to ask clarifying questions without breaking your flow.

Which subjects can Eigen tutor me in?

Eigen covers STEM, economics, law, languages, and MCAT, NCLEX, and LSAT prep. You can upload materials from any of these fields, and Eigen will create a tailored lesson. It is not limited to a single subject area, making it versatile for cross-disciplinary study.
